Kim Hyun-ah, known professionally as Hyuna, is a South Korean singer-songwriter, rapper, and model. She initially debuted as a member of the girl group Wonder Girls in February 2007, but left the ensemble shortly after. Hyuna then joined the girl group 4Minute, under Cube Entertainment, and debuted with the group in June 2009. 4Minute went on to become one of the most popular girl groups in South Korea.
In 2010, Hyuna began her solo career, focusing on "performance-oriented music." Her solo debut single "Change" reached number two on South Korea's Gaon Digital Chart. The following year, she released her first extended play Bubble Pop!, which included the title track that sold over three million digital copies and made her the first female K-pop solo artist to reach 100 million views on a single music video on YouTube.
In 2011, Hyuna collaborated with former Beast member Hyunseung to form the duo Trouble Maker, releasing the hit single "Trouble Maker." She also appeared in a successful duet rendition of Psy's worldwide hit "Gangnam Style" and later released her second extended play Melting, which featured the number-one single "Ice Cream."
Hyuna's subsequent extended plays, A Talk and A+, yielded the successful singles "Red" and "Roll Deep," respectively. Following 4Minute's disbandment in mid-2016, Hyuna released her fifth extended play 'Awesome', which was supported by her first concert tour The Queen's Back. In 2017, she formed the trio Triple H with Pentagon members Hui and E'Dawn before releasing her sixth extended play Following.
In 2018, Hyuna ended her contract with Cube Entertainment after several internal conflicts and signed with Psy's P Nation the following year. Her first digital single under P Nation "Flower Shower" became her seventh top-ten entry on the US Billboard World Digital Song Sales. In 2021, Hyuna released her seventh extended play I'm Not Cool.
